Wherein, detection module includes:
The first detection sub-module is used for detecting whether sound source information exceeding a preset loudness range exists in the audio information or not, and if the sound source information exists, masking signal output is not executed;
The second detection sub-module is used for detecting whether the sound source information exceeding the tinnitus loudness consistent with the tinnitus frequency exists in the sound source information or not if the sound source information exceeding the preset loudness range does not exist, and if the sound source information exists, masking signal output is not executed;
the determining module is used for determining that the audio information cannot mask the tinnitus frequency and the loudness if the audio information which is consistent with the tinnitus frequency and exceeds the tinnitus loudness does not exist;
Wherein, the pick-up module includes:
the noise elimination module is used for eliminating noise audio in the environmental audio information of the tinnitus patient, and the elimination basis of the noise audio is preset noise information;
The calculating module is used for acquiring the loudness peak information of the audio information in different frequency ranges, calculating the discrete degree of the loudness peak information and determining the audio information with the minimum discrete degree of the loudness peak information as preset stable audio;
and the processing module is used for obtaining stable audio through adaptive filtering processing according to the audio information of the environment where the tinnitus patient is positioned.
4. A device as claimed in claim 3 wherein processing the stable audio into a masking signal that adapts the tinnitus degree information is adjusting the signal-to-noise ratio and loudness of the stable audio such that the frequency of the masking signal is in the same threshold range as the tinnitus frequency and the loudness of the masking signal is greater than the tinnitus loudness.
5. A hearing device based on a masking therapy system, comprising:
A processor;
a memory for storing the processor-executable instructions;
Wherein the processor is configured to perform the steps of the method of any one of claims 1 to 2.
6. A computer readable storage medium, on which a computer program is stored, characterized in that the computer program, when being executed by a processor, implements the steps of the method of any one of claims 1 to 2.
